AUTOMATIC VENDING-MACHINE.

Specification of Letters Patent. v Patented June 8, 1915.

Application filed December 13, 1913, Serial No. 806,476. Renewed May 1, 1915. Serial 1%. 25,336.

Be it known that I, HANS HARTMAN, .a subject of the Emperor of Austria-Hungary, residing at London, England, have invented certain new and useful Improvements in Automatic Vending-Machines; and I do hereby declare the following to be a full, clear, and exact description of theiinvention, such as will enable others skilled in the art towhich it appertains to make and use the same. Y I This invention relates to improvements in automatic vending machines of the kind more particularly intended for-deliverypf sweetmeats, cigars, cigarettes and'the .l1ke

' .and the object of the present invention is to provide an extremely simple, reliable and efficient device to this end and further" to provide a neat and-compact contrivance which maybe readily attached tothe backs of seats in places ofpublic resortsuch as normally rests upon the top of the aforelike, 7 V

theaters, music halls, cinema halls, and the In order that this invention maybe understood, it will now be described in reference to the accompanying drawings in which p I Figure 1 is a front elevation of the machine with the covering door removed showing the parts in the'normal position. Fig. 2-is a similar view showing the position of the essential parts after thefinsertion of a coin. Fig. 3 is again a similar view showing theposition of the parts after the machine has been manipulated for the delivery ofthe goods. Fig. 4 is a side elevation of.

the essential parts of themechanism with the case in section. Figs. 5, 6 and 7 are detail views showing modified forms'of the invention I s i In carryingthis invention into practical eifect the device comprises an outer casing a wherein the goods to be delivered are designed to be contained, the said goods-where packing is necessary, being preferably put in cvlindrical formas indicated atb.

The bottom of the device comprises a partially rotatable semi cyli-ndrical tray 0 wherein the lowermost article rests. In combina tion with this tray a sliding locking plate d is provided, the lower extremity of which said delivery tray in such a manneras to prevent the same rotatlng while, 1n con unction with the locking plate ol a pivoted arm fully i or catch 6 is arranged, the extremity 'e of" which enters the slot d the locking plate (23 and prevents the same from sufficientlymoving to allow of the rotation of the. de'- livery tray. The said sliding locking plate is provided or formed with a bent up portion or arm (1 the purpose of which is to support the coin when inserted ini the coin chutein such a manner' that the coin is not allowed to drop until the delivery tray has been sufficiently rotatedto-allow the lower most article to pass into the delivery'recep receptacle for containing The case is provided withia coin slot 7 beneath. whichv is arranged. a coin'chute,v g,

the said coin chute being perforated or more or less of skeleton form whereby ready access may be had to the interior of the same and inrorder' that the insertion of coins may be prevented .after the lastof the goods'con tained in the machine has been delivered, a

flat spring in is pivoted to the back 'of the casing and normally retained in a retracted position byfithe pressureof the articlscoir-l.

of the pivoted arm or catch eis-withdrawn vated while the article isdeIivered into a lower, receptacle 7 open at each sidefiand from which thearticle may be readily re "In practice and upon a coin being inserted i i I v asvshown. at Fig. 2, thelocking extremity e inoved while "uponi the delivery trayreturning to itsnormal position, the'locking plate falls and is againengaged bywthe armsor catch a. l Y

In the. form ofinvention as shown 1 in Figs. 1 to 4, the engagement between the deliveryatray and the locking plate 1 mvided for by means of an eccentricpin y" carried by the tray and upon which the lower extremity of the locking plate rests. When the last article has been delivered,- the spring h is free to expand into the position shown in Fig. 4' and a-catch or shoulder-h formed thereon, engages the lower extremity locking plate and an eccentric pin is carried on the end of the delivery tray enters therein in such a manner' that when the locking plate has been elevated, the tray cannot be returned to the delivery position 'without the locking plate falling (Figs. 5

and 6). p

In a further modification, the delivery tray may be pivotally connected to thelocking plate as shown at Z (Fig. 7 and the device manipulated after the insertion of a coin, by fmeans of a knob or arm m secured to the locking plate and projecting through a vertical slot in the side of the casing a,

lVhat'I claim is liIn a coin controlled vending machine the combination of a containing receptacle,a rotatable delivery tray, a movable locking bar resting thereon, a lockingmember engaging into such locking bar, av chute having a curved or inclined portion which in connection w1th a pro ecting part of the locking bar forms a coin-rest for a coin of predetermined size whereby the coin disengages the locking member from the locking bar.

2. In a coin controlled vending machine the combination of a containing receptacle, a rotatable delivery tray, a vertically movable locking bar resting thereon in such a 'tiepies of this patent may be obtained for Washingtomb. C.

manner that it is raised when the tray is turned manually by a knob orlever, a looking member engaging into such locking bar,

a chute having a'curved or inclined portion which in connection with a projecting part of the locking bar forms a coin-rest fora coin whereby the coin disengages the locking member from the locking bar by lifting such locking member out of a slitprovided in the locking bar.

3. In a coin controlled vending machine,

the combination of a rotatable delivery tray with a vertically movable locking bar rest= ing thereon in such manner that it is raised when the delivery tray is rotated and closes the coin inlet until the rotated delivery tray returns to its initial position and a spring which is normally retained in a retracted position by the weight and pressure of the packages in the containing receptacle and adapted to support the raised locking bar in an elevated position thus preventing the insertion of further coins when the last package has been delivered.

4. In a coin controlled vending machine, the combination of a rotatable delivery tray with a vertically movable locking bar resting thereon in i such a manner that it is raised when the delivery tray is rotated, a coin chute, a locking member engaging a slit in said locking bar so as to prevent its movement until acoin of predetermined size is inserted into thiscoin chute, said coin chute having a curved or inclined portion which, in con- .nection with a projecting part of the locking bar, forms a coin-rest, and lifts said locking member out of its initial positionand a second slit in the said locking bar, underneath ,thefirst slit, with the object of securing the return of the locking member to a locked position with the locking bar, before said bar returns to its initial position.

5. Ina coin controlled vending machine the combinationof a rotatable ,deliverytray with a movable locking bar resting thereon, a locking member engaging said locking bar, a coin chute having a curved or inclined portion which, in connection with an arm projecting from the locking bar, forms a coinrest for a coin, of predetermined size and suports said coin. in such a manner that the coin lifts the locking member sufiiciently'to disengage it from the locking bar and where by when the locking bar is raised, by rotating the delivery tray,.the ,coin supporting arm passes above the coin, which, losing its sup- .ports, falls into the money receptacle.

6. In a coin controlled vending machine the combination of a rotatable delivery tray, a movable locking bar resting thereon, a locking catch or member engaging such locking bar which is raised when the delivery tray is manually'operated and an eccentric pin carried by the rotatable delivery tray which projects into a slit formed at the lower end of the locking bar with the object to cause both to travel at the same time.

In testimony whereof I have afiixed my signature, in presence of two witnesses.
